The event loop can be broken up into a multiplexer (the part
responsible for notifying us of I/O events) and the event loop proper,
which wraps a multiplexer with functionality for scheduling callbacks,
immediately or at a given time in the future.
Whenever a public API takes a callback, subsequent positional
arguments will be passed to the callback if/when it is called. This
avoids the proliferation of trivial lambdas implementing closures.
Keyword arguments for the callback are not supported; this is a
conscious design decision, leaving the door open for keyword arguments
to modify the meaning of the API call itself.

- If the server is not closed, wait.
- If it is closed, but there are still active connections, wait.
Anyone waiting here will be unblocked once both conditions
(server is closed and all connections have been dropped)
have become true, in either order.
Historical note: In 3.11 and before, this was broken, returning
immediately if the server was already closed, even if there
were still active connections. An attempted fix in 3.12.0 was
still broken, returning immediately if the server was still
open and there were no active connections. Hopefully in 3.12.1
we have it right.

Return the total number of bytes which were sent.
The method uses high-performance os.sendfile if available.
file must be a regular file object opened in binary mode.
offset tells from where to start reading the file. If specified,
count is the total number of bytes to transmit as opposed to
sending the file until EOF is reached. File position is updated on
return or also in case of error in which case file.tell()
can be used to figure out the number of bytes
which were sent.
fallback set to True makes asyncio to manually read and send
the file when the platform does not support the sendfile syscall
(e.g. Windows or SSL socket on Unix).
Raise SendfileNotAvailableError if the system does not support
sendfile syscall and fallback is False.

U5 US9 g)a Default exception handler.
This is called when an exception occurs and no exception
handler is set, and can be called by a custom exception
handler that wants to defer to the default behavior.
This default handler logs the error message and other
context-dependent information. In debug mode, a truncated
stack trace is also appended showing where the given object
(e.g. a handle or future or task) was created, if any.
The context parameter has the same meaning as in
`call_exception_handler()`.

The context argument is a dict containing the following keys:
- 'message': Error message;
- 'exception' (optional): Exception object;
- 'future' (optional): Future instance;
- 'task' (optional): Task instance;
- 'handle' (optional): Handle instance;
- 'protocol' (optional): Protocol instance;
- 'transport' (optional): Transport instance;
- 'socket' (optional): Socket instance;
- 'source_traceback' (optional): Traceback of the source;
- 'handle_traceback' (optional): Traceback of the handle;
- 'asyncgen' (optional): Asynchronous generator that caused
the exception.
New keys maybe introduced in the future.
Note: do not overload this method in an event loop subclass.
For custom exception handling, use the
`set_exception_handler()` method.
